What is the speed of an electron that has a de Broglie wavelength of 100. nm?
Advocard [28]

<u>Answer:</u> The speed of the electron is 7.24\times 10^3m/s

<u>Explanation:</u>

To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:

\lambda=\frac{h}{mv}

where,

\lambda = De-Broglie's wavelength = 100nm=100\times 10^{-9}m

h = Planck's constant = 6.6\times 10^{-34}Js

m = mass of the electron = 9.11\times 10^{-31}kg

v = speed of the electron = ?

Putting values in above equation, we get:

100\times 10^{-9}m=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times v}\\\\v=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times 100\times 10^{-9}m}=7.24\times 10^3m/s

Hence, the speed of the electron is 7.24\times 10^3m/s

Elements that form ionic bonds generally have how many valence electrons?
asambeis [7]

Answer:

they should have a number that can completely transfer and fill the other atom

Explanation:

example:

sodium(2.8.1)and Chlorine(2.8.7)the sodium will give chlorine the 1 valence electrobo so they both become stable(2.8)±and(2.8.8)–

magnesium(2.8.2)and oxygen(2.6)same way as above to abtain mg(2.8)±²and oxygen(2.8)–²

Which of these materials is an example of a conductor? (of electricity)
Sidana [21]
I think it would be wool fabric, D. Because when you get a piece of wool fabric and rub it against a balloon it creates static electricity. Hope I helped some :)
